Berlin's fare zones, and the one that catches everybody
Berlin sells tickets by zone, and the zone names imply three equal thirds. Two of them are the city and the third is mostly the airport, which is where the wrong ticket costs money.

Berlin prices public transport in three concentric rings, and the names suggest three comparable pieces. They are not comparable. Two of the three are the city and the third is mostly what lies beyond it, including the airport.
What each ring contains
Zone A is everything inside the Ringbahn, the S-Bahn loop around the middle of the city. Almost everything a visitor plans to do sits inside it.
The area from the Ring out to the city boundary is zone B. That covers most of residential Berlin and a large share of the parks.
Outside the city limits is zone C. Potsdam is in it. So is Berlin Brandenburg Airport, which is the part that catches people, because a ticket covering the entire city still does not reach the airport.
The ways through it
An ABC ticket covers all three zones and therefore covers the airport by definition. It costs more than the AB equivalent and removes the question instead of managing it.
The Deutschlandticket is a monthly subscription covering local and regional transport across Germany, which includes every Berlin zone and both airport runs. For a stay longer than a few days the arithmetic usually favours it.
An extension ticket, the Anschlussfahrausweis, tops up an AB ticket for a single journey into zone C. It is cheap and it has to be bought twice, once each way, which is where it tends to go wrong.
The check worth running
Ask whether the trip touches the airport or Potsdam. If it does, you need C. If it does not, AB covers the whole city and you will not run out of it.
Where this comes from
Unlike most of what is published here, this post is not drawn from the research corpus. The corpus contains no fare data at all: its transport figures are journey times from the BVG journey planner, not prices or zone rules. What is above is general knowledge about how the tariff is structured, and the zone geography is the stable part of it.
Prices and product names change, and this page carries no prices for that reason. Check the current fare on the BVG site before travelling. If you find something here that is out of date, it is a mistake rather than a simplification.
